Myeloperoxidase (MPO) activity after hind paw incisions. For these experiments MPO activity was measured in peri-incisional skin as an index of infiltrating neutrophil activity. Skin was harvested from separate groups of mice at the indicated time points and processed for MPO assays as described in Methods. The time course for analysis was the same as that used for the behavioral and cytokine assays. Statistical analysis failed to detect between group differences at any of these time points. N = 8/group.
